To all whom it may concern:A

De it known that I, FRANK RADEMACHER,4

bustion or for the production of gas for subsequent consumption.

Another object is to provide practical means for using for fuel, crude petroleum of very 10W gravity and great consistency and viscosity which cannot be successfully used'as fuel by any of the meansl or methods heretofore known.

Another object is to provide a fuel sup-V plying apparatus Which Will eliminate from crude oil any contained Water, and will supply the fuel to a furnace or gas retort in a refined and highly fluid condition, Without any loss of its light or volatile combustible constituents.

Another object is to provide means Whereby the use of liquid fuel on steam vessels may be divested of all danger from explosive gases forming in the storage tanks...

By this invention fuel Which will not ignite except at high temperature can be successfully used and itlis made practicable to supply the oil storage tanks of Steamers with heavy loW gravity crude'petroleum which is not at all liable at ordinary temperatures to produce explosive or combustible gases, and to Ause said oil with the utmost convenience jand with the highest efficiency.

A further object is a great reduction in the cost of'fuel, utilizing the cheapest`l grades of oil WithoutI any refinery cost or Waste.

The accompanying drawings illustrate the invention.

Figure -I'is a plan partly in 'section and broken in part, illustrating apparatus embodying this-invention. II is a fragmental elevation of the same, partly sectioned and broken in part to contract the View. Fig. III is an unbroken diagrammatic elevation on a smaller scale, the parts being rearranged for convenient illustration. Fig. IV is an axial vertical section ofthe heater and Water separator shown in Ifigs. Iand II. Fig. V is a plan of the head of the oil chamber of the heater.

1 is asource of oil supply, comprising au oil chamber communicating with a vertical nipple 2 open at its upper end.

3 is a heater in the form of an oil-heating chamber or tank; 4 a pressure chamber connected with the heater; 5 an atomizer; 6 a pump connected to pump oil from the oil chamber to the atomizerf) through the heater 3 under pressure of the pressure chamber 4c.

7 is a relief and overflow-pipe for conducting tothe oil chamber 2, heated oil which comes from the heater 3, and 8 is a pressureregulator for the relief pipe 7 for ijegulating the pressure in the pressure cham- 9, 10 designate an oil supply pipev Which, in connection with the oil pump 6, forms a conduit from said chamber to'the heater 3. The portion 9 of said pipe leads from the oil chamber 2 to the pump 6, and the portion 10 leads from the pump to the heater chamber 11.

12 is a hot-oil pipe leading from the heater 3 to the pressure chamber A and openin into suchchamber near the bottom thereof?i 13 is the hot-oil discharge pipe which leads from the vpressure chamberabove the mouth a of the hot-oil pipe 12 and has tWo branches, one of Which, 14 is the supply pipe forv the atom-izernozzle 5, and the other, 7 is a relief 'and overfiow pipe controlled by the pressure regulator 8 and leading to the chamber 2. for the double purpose of first allow' ing a regular action of the pump and second supplying hot oil for Warming oil in chamber 2 before it enters the supply pipe 9. The main oil supply reservoir 1 is, it Will be seen, rovided with a contracted extension 2, said extension forming a supplemental oil chamber into which surplus hot oil is returned through relief ipe 7. The oil supply pipe 9 leads from said contracted extension 2 into which pipe 7 empties. This construction avoids mixing any ofthe heated oil with the main body of cold. oil in the supply 1, and also -tends to make `the oil Warmer and less -viscidwhere it enters sup-l Valves 17, 18 are check valves for con trolling the oil.l The valve 19 regulates the amount ofA oil supplied to the atomizer nozzle .5.

2O designates a'live steam pipe for theA atomizer-5.

21 designates any furnace, retort, or other receiver or converter intowhieh the hot oil may be discharged asrequired.

22 is 'a Valved impurity draw ofi' pipe leading from the bottom of the chamber 4 for the purpose of removmg any Water or other foreign substance or impurities Which may collect at the bottom of the pressure chamber. f

23 is an indicator stand pipe in which a float ,24 plays up and down to move the indicator25 to indicate the depth of oil .in the supply tank 1.

The heater is desirably constructed as shown in detail in Figs. IV and V. 26 and 27 are tube sheets having annular grooves 28 into Which the ends of a shell 29 are fitted by ground jointsto prevent any leakage of oil. The tube sheets 26,27 are held in place by rods 30 passed therethrough outside the shell and secured by nuts 31.

32 and 33 are hollow heads fitted steam tight, yby rinOs of packing 34, on the ltube sheets and hdld in place by means`of a rod 35 extending through the heads 32, 33 and Secured by nuts 36. Packing 37 and a washer b are interposed between the nuts 36 and the heads 32,33. Tubes 38extend between the tube sheets, being expanded into. perforations 39 therein thus forming an oil tight chamber 11 Within the shell 29 and between the tube sheets 26, 27, The heads 32, 33 form distributing and receiving chambers for passing the exhaust steam from pipe 16 through' the tubes of the heater and to the 'final exhaust pipe 40.

Any other means for transforming the oil from a li uid to a vapor or gas may be substituted or 'fthe atomizer and converter yvithout departing from the spirit vof the invention.

i By providin means for Warming the oil in the oil cham er away from the 'main body of oil in the tank or other source of supply, very thick crude oil may be pumped 'to lthe heater and there, under the heat from the exhaust steam, the oil may be brought to a high degree of fluidity; and when this highly heated and highly -tluid oil is allowed to stand in the pressure chamber under pressure of the contained air, then Water and lother contained impurities, if any, fall to the bottom and may be drawn oil' through the cock 22.

By supplyingahighly heated oil to the atomizer, converter or other means for transforming oil to a vapor or gas, I am able to gain a great economy but this involves a method which is claimed in an application for patent, Serial No. 141,754, filed contem- .poraneously herewith.

41 is a live steam pipe connecting With the exhaust pipe 16 for supplying the heater 3 with .live steam for heating the oil independently of exhaust .from the pump. This has a.' double use, viz., 1st, to heat the oil before starting the atomizer or pump', 2d to supply additional heat 'to the oil When the exhaust steam is insuiiicient. 4 i

The outlet end of the pipe 7 Which is a branch from the pipe that conveys the hot oil to the va orizer 1s submerged in oil near the intake o the oil supply pipe 9 as as to prevent the escape of volatile portions of the oil into the atmosphere.v

y 45 is a gage on the pressure tank.

42 is a cock at the bottom of the heater to draw 0E the 'impurities Which v may deposit in theheater. y

The oil sup ly pipe `enters the heater at a considerable istance above the bottom of the heater so that the im urities which settle therefrom will not be isturbed by the inflowing oil. The hot oil pipe opens from the heatery as near the top as possible so as to utilize all the space of the heater, and so that in lling the heater the oil may force the air out into the pressure chamber through the hot oil pipe.,

43 is a valve on the final exhaust pipe by which `the same can be controlled for the purpose of increasing the pressure, and consequently the heat in the heater. The livev steam by-pass pipe 41 has a valve 44 which v which the valve 44 may be closed, the final exhaust valve 43 fully opened and the pump 6 and the atomizer 5 start-ed into operation.

The gage 45 enables the voperator to adjust the regulatory 8 to the proper pressure required for supplying oil to 'the atomizer. -A pressure of ten pounds is sutlicient for this purpose under ordinary conditions.

What I claim and desire to secure by Letters-Patent ,of the United States is v 1. In a liquid fuel supplying apparatus,

from the steam pump through the heater, a relief-pipe for conducting heated oil from the heater to the nipple, and a pressureregulator for the relief-pipe,

2. In a liquidfuel supplying apparatus,

,a vertical nipple open at the top, an oil chamber communicating with the nipple, a heater, a steam pump connected to pump oil from the nipple through the heater, an eX- haust-pipe leading from the steamI 4.pump through lthe heater, a relief-pipe discharging hot oil from the heater into the nipple, and a ypressure-regulator for the relief-pipe.

3. An atomi'zer, a main oil supply reser- Voir provided with a contracted extension, an oil-heating chamber, a. pressure chamber, means for supplyinghot oil from such heating chamber to the pressure chamber, means for supplying hot oil from the pressure chamber to the atomizer, a pressure-regulator for regulating the supply 'of hot oil from the pressure-chamber to said contracted extension of the supply reservoir, and means for moving oil from said extension-to the t hot oil-supplyin means.

4. A source o oil. supply, a heater, a conduit therebetween provided with a ump, a pressure chamber, a pipe leading om the .heater to the chamber near its bottom, and a branched pipe leading from the chamber above the inlet of said pipe, one branch of which communicates with the oil supply and the other one leads to the point of consumption.. i 5. A source of oil suppl-y, a vertical heater communicating therewith, a vertical pressure chamber, a pipe leading from the top of the heater nearly to the bottom of the chamber, a steam pump, the exhaust from which communicates with the heater, adjustable means fo'r permitting the steam to escape from the heater, means at the bottom of the chamber for emptying the same, and a. pipe leadin from the chamber at a point above'the out et of the pipe from the heater to the point of consumption.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses, at Los Angeles, in the county of Los Angeles and State of California, this 23rd day of January, 1903.
